Tokyo Ghoul is a Japanese dark fantasy manga series by Sui Ishida. It was serialized in Shueisha’s seinen manga magazine Weekly Young Jump between September 2011 and September 2014 and has been collected in fourteen tankōbon volumes as of August 2014. A sequel titled Tokyo Ghoul:re began serialization in the same magazine in October 2014 and a prequel titled Tokyo Ghoul Jack ran online on Jump Live.
The story follows Ken Kaneki, a college student who barely survives a deadly encounter with Rize Kamishiro, his date who reveals herself as a ghoul. He is taken to the hospital in critical condition. After recovering, Kaneki discovers that he underwent a surgery that transformed him into a half-ghoul. This was accomplished because some of Rize’s organs were transferred into his body, and now, like normal ghouls, he must consume human flesh to survive. The ghouls who manage the coffee shop “Anteiku” take him in and teach him to deal with his new life as a half-ghoul. Some of his daily struggles include fitting into the ghoul society, as well as keeping his identity hidden from his human companions.
